TEERMOSTATIC RADIATOR. CONTROL.

Application filed August 26, 1922. Serial No. $4,421.

To all whom it may concern.'

Be it known. that I, CHARLES C. MODER- MOTT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Thermostatic Radiator Controls, of which the following is a specification.

This invention relates to controls for heating radiators, and an object of the invention `is to provide a window operated thermostatic control for automatically shutting off the passing of a heating agent through a radiator when the window is open, and which will permit the passing of the heating agent through the ra iator when the window is closed.

In. hotels, oliice buildings, rooming houses and apartments, as well as dwellings, when the room becomes too hot the occupant opens the window and when the window is opened for cooling off the room it places an extra burden upon the heating system of the building causing practically the heating of the out doors and consequently requirin the use of a greater amount of fuel an the needless waste of heat, and it is an object of this invention to provide a structure for overcomin this needless waste of heat, by cutting o the passage of the heating agent through the radiator when the window is open, and then when the room is suiiiciently cooled the natural instinct of the occu ant will cause him to close the window at w ich time the radiator valve will be reopened to permit the heating agent to pass through the radiator.

According to my present invention I rovide means for conservin the heat w .ich would otherwise be lost w en a ventilating device such as a window is made active and puts an artiicial demand upon the heating device or heat supplying means. There is no advantage in attempting to sup ly heat to the room if the rate of loss excee s a predetermined value. That is to say, it the ventilating device such as the window is put into operation and its ei'ectis such as to dissipate the heat needlessly or at too great a rate, the heating device might Just as well be cut oiin as soon as the ventilating dev ice is put into operation. My present invention provides a novel method of and means for accomplishing this result.

-plurality of this 'invention is to structure as specified in which a of circuit closers are carried by the window structure and are connected, through a plug switch with a thermostat which in turn controls a valve of approved construction which controls the assage of the heating agent through the ra iator.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawin wherein:

ig. 1 is a diagrammatic view illustrating the application of the improved system or control mechanism.

Fi 2 is an enlarged view partly in section illustrating the circuit closers and their wirinfg connection with the thermostat.

Re erring more particularly to the drawings, the improved radiator-control comprises, in combination with a thermostatically controlled valve 1, of approved type, such as can now be purchased on the open market, a thermostat structure 2 also of approved type and purchasable on the open market, a plurality of circuit closers generically indicated by the numeral 3 and which are carried by the window frame 4.

The circuit closers 3 comprise contact plates 5 which are connected by suitable electric conducting wires 6 with one terminal 7 of a plug switch structure 8. A contact sleeve 9 is embodied in each of the circuit closers 3 and these sleeves are connected by suitable electric conducting wires 10 with the lug switch structure 8, thereb permitting t e cutting in of anyone or a l of the circuit closers 3 in circuit with the thermostat 2 and battery or other energizing source 12. The circuit closers 3 are laced at pre-determined spaces along the lieight of the window frame 4, a plurality of them bein provided for use in connection with the lower sash 13 and one with the up er sash 14: so that the operation of the va ve 1 can be caused by the raisin of the lower sash 13 at various hei lits, w ile the valve will be operated imme iately when the upper sash 14 is o en.

Specifically t e circuit closers 3 include, besides the contacts 5 and contact sleeves 9, movable pins 15 which slidably enga e in the sleeves 9 and extend through an are insulated from the contacts 5 y suitable A further object provide a insulating plates 16. Contact discs 1 7 are carried by the pins 15 and these pins are urged outwardly by means of springs 18. The lower sash 13 is provided with a longitudinally extending groove 19 extending upwardly from this lower end, so that as the lower sash 13 is raised the groove 19will move in alignment with the pin 15 of one of the circuit closers 3, permitting the spring 18 to force the pin 15 outwardly and move the disc 17 into engagement with the contact 5 thereby closing a circuit through the circuit closer and if the plug switch structure 8 is set to permit operation of the thermostat 2 by the said circuit closer 3 which has been operated, the current will be permitted to flow through the thermostat 2, causing heating of the thermostatic metal, by the resistance coil 20, which is coiled about the stem 21 of the thermostat 2, thereby operating the thermostat in the same manner in which it would be operated by the heating of the room to the necessary temperature. .The operation of the thermostat 2 will in turn operate the valve 1 and cut oli the passage of the heating uid through the radiator 22. When the -window is closed the circuit will be cut oft' and the thermostat 2 will be permitted to act in its usual manner for controlling operation of the valve 1 and if it is so desired, all of the circuit closers 3 may be cut out of circuit with the thermostat 2 to permit it to operate independently of the circuit closers.

In oice buildings, hotels or the like where a number of windows are provided all of the switches on the same level, may be connected in a one wire arrangement, so as to permit control of the radiator valve by operation of anyone of the windows, and by connecting them up to the necessary thermostat in the one wire manner considerable ex ense is eliminated.

t is, of course, to be understood that the invention may be constructed in other manv ners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.
